a right angeled isosceles prism ABC is made of glass of r.i 1.352. A thin glass plate of thickness 3mm and r.i 1.5 is cemented in the hypotanuse AC of the prism. A ray of light is incident on one of the equal faces AB. What should be the angle of incidence if the ray is to pass through the thin glass plate undeflected?
